4.3.9.4  Hardware configuration   (P052 = 4) 
This function is used to select option boards (SCB, CB, TB) in the rectifier/regenerating unit electronics box.  
In order to install these modules, an LBA bus coupling (Local Bus Adapter) is required for the electronics box 
(see Section 9.1)! 
All parameters, which can be written into the "Hardware configuration" status ("H", refer to the right-hand 
column in the parameter list in Chapter 5), can be changed. 
The "hardware configuration" selection can be realized in the "Switch-on inhibit", "Ready-to-switch" or "Fault" 
status 
 
Procedure:
 
⇓  P052 = 4  Function selection   Hardware configuration  
 
⇓  P051 = 3  Access stage   Expert mode ( to change the following parameters) 
 
⇓    Set the parameters to configure the optional board (see Section 4.5 or the 
operating instructions for the board) 
 
⇓  P090 =   Board, slot 2  (To the RIGHT
 in the electronics box!) 
  P091 =   Board, slot 3  (In the CENTER
 in the electronics box!) 
  Parameter values for P090/P091: 
    0:  No option board 
    1:  CB  Communications board 
    2:  TB  Technology board  (only P090
) 
    3:  SCB  Serial Communication Board 
 
⇓  Additional parameters, depending on the option boards (refer to the associated Instruction 
Manuals or Section 4.5) 
 
⇓  P052 = 0  Function selection   return 
 
⇓  P key  The operating display appears (r000) while parameters and interval variables 
are being re-assigned 
- The hardware is initialized 
If error/fault message F050, F070 or F080 appears: see Chapter 7 
 
⇓  After the selected function selection has been completed, the "Switch-on inhibit" (008) or 
"Ready-to-switch-on" (009) operating display appears.
